Ninigret (also known as Juanemo according to Roger Williams) (c. 1610-1677) was a sachem of the eastern Niantic Indian tribe in New England at the time of colonization, based in Rhode Island. In 1637, he allied with the colonists and the Narragansetts against the Pequot Indians.

Ninigret is credited with keeping the Niantics out of King Philip's War,
